Door to Door Water Testing

Door to door water testing
Excerpt from Ontario’s Chief Drinking Water Inspector’s 2008-09 Annual Report - Ministry of The Environment

If a test of your tap water produces a brown substance is it safe to drink? Truth is, such tests are absolutely meaningless in terms of assessing water safety. Unfortunately, some door-to-door salespersons have been causing unnecessary concern as a way of luring Ontarians, especially seniors, into buying costly reverse osmosis treatment units.

How do the tests work? First, an electric current is used to activate naturally occurring minerals and make the water turn brown. Then, the treatment removes the minerals from the tap water, making the brown colour disappear. The test does not and cannot identify contamination that could cause illness.

“In Ontario, only fully accredited laboratories licensed to perform drinking water testing – not home-based testers – are authorized to perform health-based tests on drinking water,” said John Stager, Ontario’s Chief Drinking Water Inspector. “Our stringent standards for these labs make the province’s municipal tap water among the best protected in the world. Ontarians can have confidence that their tap water is safe to drink.”

Stager further recommends: “If you have been approached by someone offering to test your drinking water, I advise you to immediately contact your municipality, or your local health unit. They can answer any questions you may have. If a salesperson claims that your drinking water is unsafe or claims to be testing the safety of your drinking water, please contact the Ministry of the Environment immediately and we will follow up.”
